Abstract

The Hubble Space Telescope High Speed Photometer (HSP) has successfully completed orbital and science verification testing and is currently executing scientific proposals. The performance of the HSP has been satisfactory except for sensitivity of one of the detectors and low transmission of the prism apertures used for two color photometry. The impact of the telescope performance and ground system limitations on instrument performance is discussed. The HSP's use of the telescope is unique in several respects. Target acquisition depends critically on knowledge of aperture locations and the ability to execute precise small angle maneuvers. The HSP requires precise spacecraft scans for occultation observations. The photometric performance of the HSP is especially dependent on spacecraft pointing stability. The HSP's time series data do not naturally fit into the image oriented data format of HST.
